He was a hero that was loved. He was a boy that had a good heart.
But that person is gone.
Now he is cold, sad and lonly and it was all their fault.
That smiling guy is dead he is now only a shadow of what used to be.
He is Chaos's son and only joy.
He must go back and save the universe from Order, Chaos's brother.
Will he survive?
More importantly, is he even who he think he is? Or is he someone else?
